The truck is in the plastic stage and I am going to order paint for the exterior, interior will be a different color including doors and was wondering how much paint will be needed, inside of bed will be painted body color but firewall will be a satin black to match rest of engine compartment, also who did you order from, color is going to be sea foam green on a ‘56 short wheel base, thanks, Pete
The type of paint and mix ratio will have a bearing on this . I would think that color should have pretty good hiding characteristics ( less coats to cover ) and is a pretty basic color so my guess would be 3 quarts with a single stage 4-4-1 mix . As a bodyman I will be getting extra because as careful as anyone is mixing it is it's not uncommon to have slight differences in separate mixes .
EBEAR...what are the components in your 4-4-1 mix?
OP..coverage is only one concern, how many times you have to redo a panel is another. Even seasoned pros have spray-outs that go south and require a respray, always good to have extra paint on hand. I like to spray a sealer coat that is similar in color to the top coat, this cuts down on the material needed to cover and it also makes for a smoother, more durable (less chipping) finish.
Another question would be are you painting the truck fully assembled, or each part separate? You'll use more paint painting each piece separate, but you'll have a more professional looking, and better detailed job in the end. (if you can put it together without damaging anything, and needing to redo something) Having extra paint left over that matches isn't a bad thing.
Yes sealer is a great idea which I also use , but other than bleed through if you have total coverage it shouldn't really mater what color is underneath . The 4-4-1 I referred to is paint that calls for 1 part paint 1 part reducer and 25% hardener . There are allot of paints that use 4-2-1 which of course gives you less spayable product but coverage is usually quite similar per mixed quart . I was aware of the smoother finish any easier coverage but not of any increased durability using sealer .
I use HOK KD3000 sealer. It has a very high adhesion factor which means that gravel and door dings won't cause the paint to chip at the impact point. It also provides for better adhesion for the top coat which further adds to the durability. That said, if you spray a crappy top coat paint on top of it you will get what you paid for. I use HOK products almost exclusively...the reducers are "hot" which means that if you have anything on the prepared surface that may interact with the top coat then these reducers will find them. I hate crinkles!
